I am currently trying to develop a web app utilizing the htp.p built in to generate out the html/javascript code. I have a procedural / "best way to handle" type question.

I am generating an html table. There are field labels and then data that is coming from the database. When the query returns "No Data Found" or when a null is returned, I need the html table to include a ' ' to retain the html table formatting.

Likewise is I am executing a cursor and filling up a table and the cursor returns no rows, I still need the table definition and the field headings.

What is the best practice for dealing with these situations?

I have tried using nvl in the query, but if the datatype is numeric or date, then I can not use nvl(column, ' '). Liekwise if I do a "select into" and the variables have a default value of ' ', if the data that I am getting from the database is numeric or date, I get a datatype mismatch error.

Any ideas?
